The power trunk pull down has stopped working. I tested the motor and that works fine in both directions. Is there a switch somewhere that activates the motor? 2002 and earlier years showed the switch on top of the motor, but, 2003 is all different. Is there a mechanical switch somewhere that triggers the motor action or is the motor triggered electronically?? I did find an small electonic box that can be unplugged from a harness in the trunk where the power for the pull down comes from as well as the trunk lighting. Thanks!
